How does Slide calculate pullout strength for stability analyses? What input parameters should be used for pullout adhesion for geotextiles?

The GeoTextile support type can be used to model the various types of slope reinforcement which are used in the form of meshes, grids, strips, etc. There are a wide variety of such support systems, referred to as geo-textiles or geo-fabrics, geo-grids, geo-synthetics etc.

Although the term “GeoTextile” actually refers to a specific category of reinforcing materials, for the purpose of the following discussion, the term “GeoTextile” will be used to refer to all forms of flexible planar reinforcement, which are used in the form of fabrics, meshes, grids, strips, membranes, etc, to reinforce slopes. This includes both synthetic (polymer) and metal (e.g. steel strip) reinforcement.

A good starting point to get more information is the Overview of Support Implementation help topic in Slide, which applies to all support models.
